The management of color is more difficult. When the 
long duration of the flowering season is considered, it will 
be obvious that it is impossible to keep up the show of a 
single border or plot for six months together, and conse- 
quently, that much of the labor employed in mixing colors 
is misspent, since plants, as they are commonly arranged, 
come dropping into flower one after another: and even 
where a certain number are in bloom at the same time, 
they necessarily stand apart, and so the effects of contrast, 
which can be perceived only among adjacent objects, are 
entirely lost. To obviate this defect, it has been recom- 
mended that ornamental plants should be formed into four 
or five separate suites of flowering, to be distributed over 
the garden. Not to mention the more vernal flower, the 
first might contain the flora of May; the second that of 
June; the third that of July; and the fourth the tribes 
of August and the following months. These plants should 
be kept in separate compartments, arranged either singly 
or in masses; but the compartments themselves should be 
so intermingled as that no particular class should be en- 
tirely absent from any one quarter of the garden. The 
May parterres should, however, chiefly occur in the vicinity 
of the green-house or conservatory, or, when these are ab- 
sent, in a warm sunny situation. The flowerings of June 
and July, as being highly showy, should occupy the most 
conspicuous parts of the garden. The autumnal peren-
